No; but the investigation is 6 years after Miller was at X; and that the Federal statue of limitations is generally 5 years for bribery and fraud.

Under federal statute 18 USC 3282, individuals are protected from prosecution for any noncapital offense in which an indictment is not found within five years of the criminal act

So if there was any similar activity discovered at XU, you think the NCAA would ignore because the federal statute of limitations ran out? I think it's highly unlikely XU suffers any blowback, but it would be an eye opener to find out he ran this racket at XU too.
